Kneadatite Blue/Yellow (Green Stuff) is a two-part epoxy/polyamide sealant/adhesive for interior and exterior maintenance and repair. It has excellent adhesion to stone, ceramic, metal, wood and many plastics, including vinyl.
Nicknamed Green Stuff by sculptors and modelers, Blue/Yellow is well-known for its long worklife, non-grainy texture and ability to hold fine detail. Cured models withstand up to 4 vulcanizations. Blue/Yellow is not intended for structural applications.
Blue/Yellow is 2 round bars in a reusable plastic tube.
How to use: To achieve optimum adhesion, surfaces should be scuffed and/or lightly sanded and cleaned free of grease or dirt prior to application.
Mix by kneading with damp fingers to a uniform color. Any length contains the correct ratio of base to curing agent. Apply within 1 hour of mixing.
Bars: Cut or twist off 1 part blue curing agent to 1.5 parts yellow base. Mixing proportions can be adjusted to control cure time and hardness: more blue produces a faster, harder cure; more yellow results in a slower, softer cure. Mix by kneading with damp fingers to a uniform color. Apply within 1 hour of mixing.
Blue/Yellow has a 1 to 2 hour work life, Functional cure occurs in 4 to 5 hours when Blue/Yellow can be drilled, sawed, carved, sanded, stained, and painted. Ultimate hardness is reached in 20 to 24 hours. Cured color is green.
